I think TA is signalling that very soon Knob will hit George. I notice a rather agressive tone when George does something he doesn't like, he seems to be getting angrier and angrier with George. I wonder if he will hit George and that will finally force 'wet behind the ears' Hellin to finally do something. Maybe she will kill Knob thus getting rid of an unpleasant character and also putting herself away in Jail for several years. Hooray! As you can gather I dislike Helen intently, always have; her lack of backbone is really annoying.
As for the shop, there is no way that the shop can support all the people who seem to rely on it for their income. Sometimes TA really pisses me off with their patronising, they really underestimate the intelligence of their listeners if they think we swallow it.
There have been several rather clumsy exposition type scenarios which just don't sound right. Where the character describes something in detail to another person when they both obviously know it. The only reason they say it is so that the listeners understand some topic. It is clumsy and can be better achieved in a much more realistic and natural why if the script writers put some more effort into the writing. Come on TA, buck up with your plot lines and dialogue; get some decent script writers.
